Ruston Plumbing Code Explained: What Every Homeowner Needs to Know

Whether you’re planning a kitchen remodel, adding a bathroom, or just replacing an old water heater, understanding the plumbing code in Ruston is essential. Even though Ruston is a small town nestled next to Tacoma, its plumbing regulations follow many of the same standards as the City of Tacoma and Washington State Plumbing Code.

This guide will help you understand the basics of plumbing permits, inspections, and homeowner responsibilities—so you can stay code-compliant and avoid costly penalties.

🧰 Do You Need a Plumbing Permit in Ruston?

Yes—in most cases, plumbing work in Ruston requires a permit. If your project involves new piping, fixture replacements, water heater installations, or drainage modifications, a permit is usually necessary.
The City of Ruston utilizes Tacoma’s permitting system and follows the 2021 Uniform Plumbing Code (UPC) as adopted by Washington State.

Common Projects That Require a Permit:

Installing or replacing a water heater
Repiping water supply or drainage systems
Adding or relocating plumbing fixtures (sinks, toilets, showers)
Installing a new dishwasher or washing machine drain
Connecting to or modifying a sewer line

🚫 When Is a Permit Not Required?

There are a few minor tasks that don’t require a permit, such as:

Replacing a faucet (without touching supply lines)
Repairing leaks in accessible pipes
Clearing a clogged drain (as long as it doesn’t involve cutting into piping)

However, always check with the City of Tacoma Permit Center to confirm. What may seem minor could still require documentation if part of a larger plumbing system.

🛠️ Who Can Do Plumbing Work in Ruston?

In Washington State, most plumbing work must be performed by a licensed plumber. Homeowners can do certain projects themselves only if the property is their primary residence and they follow all applicable code requirements.

You can do your own plumbing if:

You own and live in the home
You pull the necessary permits yourself
You schedule the required inspections

However, plumbing in multi-family buildings or rental properties must be done by licensed professionals.
